THREAD-BOARD FOR SEINNING, TWISTING, AND THE LIKE MAG HINES.

all whom may concern a that I, ALBERT H. MORTON, United States, residing at of Middlesex and State doiiing rail for block from turning when the bolt is screwed into it. In order to secure the alinement of the hole in the block with the bolt, .the up- 'Be it known a citizen of the Lowell, in the county of Massachusetts, have invented certain new per inside edge of the block 14: is chamfered, and useful Improvements in Thread-Boards as shown at 15, so as to permit the hlockto for Spinning, Twisting, and the Like Maclosely en a e both the rear surface 0 the chines; and I do hereby declare the follow- 'dependlng flan e 12 and the lower surface ing to be a full, clear,'and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to an improvement in, thread-boards for spinning, twisting and the like machines. The object of the invention is to reorganize and improve the construction of thread-boards, and to this end the invention consists of the thread-board hereinafter described and particularly defined in the claims. In the accompanying drawing illustrating the preferred form of the invention, Figure 1 is a sectional elevation of the elevation; Fig. 2 is a plan view of the same; Fig. 3 is a section on the, line 3-3, Fig. 2; Fig. l is a section ig. 3 Fig. 5 is a section on the line 55, Fig. 3; and Fig. 6 is a section on the line 6-6, Fig.3, looking in the opposite direction from Fig. 5. The roller beam 1 has attached to it brackets 2 which support the dotting rail 3 which in turn supports the thread-board 4: having at its outer end the thread guide or finger 5. The doiling rail 3 is made of sheet metal, of about 18 gage, pivotally supported at 6 2, so that it is adapted to ft all of the guides for dofiing. The projection 7 on the front of the bracket serves to support the threadboard in operative position. The threadboard 4 consists of a casting having .a smooth continuous upper surface stiffened by flanges 8 at its sides and front. At the rear of the thread-board are two cars 9 which receive the hinge pintle 10. The thread-board supbolted to the depending flange 12 of the doffing rail 3 by a bolt 27 which passes through an elongated hole 28 in the support 11 and through a hole in the depending flange 12 of, the dofling raiLEl' and screws into a screwthreaded opening in the block 1a of the doflingrail 3. A washer 16 is located under the head of the bolt. It will-be observedthat the support 11, by loosening the bolt, may be adjusted to the right or left within the limits of the elongated opening 28 so as to bring the guide directly over the spindle, and that it may then be clamped in adjusted position and securely held there by screwing the bolt into the block 1a which rigidly clamps the support to the dofiing rail, The forwardly projecting lower edge of the flange 12 of the doiling rail accurately positions the thread-board per portion of the support 11 is provided with cars 17 at its ends which have holes to receive the pintle 10. From the front of each of the ears 17 there projects forwardly a lug 18 which is adapted to engage the under surface of the thread-board casting so as thereby to support the fingerhead in horizontal position. The surfaces of these lugs 18 are comparatively small and i may be easily machined or filed, ifnecessary'; to ear gage the under surface of t casting so as to hold tl:-. position. By reference to r lg. seen that the cars project ream yond thebody of the eadhr The space left between the by providing the upper edge of he 11 with a forwardly projecting closes the opening between the ears on the rear of the thread-board and prevents dirt from entering taining access to the pintle. l't alsomakes the upper surface of the part smooth and unobstructed by an'opening which would be liable to catch the brush to clean the top of the frame. The thread guide 5 consists of a bent wire, of ordinary form at its forward end, provided with a flattened'shank 2-0 screwthreaded at 21 and projectingithrough correspondingly shaped holes in the central portion 22 of the depending fiange 8 on the front of the threadboard casting and through a second hole in the lug 23 near the center of the underside of This block 14 is triangular in general outline, having one straight side engaging the horizontal portion of the lip on the a lip l9 which L the opening and. thereby ob-' or other thing used the purpose of holding the support ll with relation thereto The upthe thread-board casting. A nut 24 em-' braces the threaded shank 120 of the thread guide and afi'ords provision foradjusting it out and in. This nut'is slotted at 25 upon opposite sides. This slot extends through the threaded portion of the nut 24, which is made of such a size as toresiliently and tightlyjfit the shank 20 of the thread guide.

By insart-ing a flat instrument in one of the slots 25 the nut may beturned in the'one direction or the other to adjust the thread guide in or out. The fact that the nut is slotted and resiliently engages the shank of the thread guide, secures it from accidental displacement, and the further fact that the nut requires a special tool or contrivance for .use in turning it, insures the protection of It is adequately supported in operative position. It presents no openings to collect dirt or catch the cleaning brush. The thread-board may be adjusted longitudinally of the dotting rail with facilit and securely fixed in adjusted position. T is lower lip on the front edge of the dofiing rail eilicicntly operates to hold the thread-board horizontal, andthe. t-hread' guide is not only securely fixed in adjusted position, but is capable of being easily adjusted to different positions, and it is, moreover, free from meddling adjustment by the operative.

The invention is not limited to the illustrated embodiment as it may be embodied in other forms within the scope of the following claims.

I claim- 1.
